Excellent presentation ! In particular, the fact that you went in to the trouble to disassemble the drill and build a wooden stand - to show us the function of the motor - is really remarkable. Also, the idea to use small battery and magnet was just brilliant. It is funny, but this is the best video I have ever seen on electric motors, and it comes from a ...woodworking channel !
You are really wonderful at explaining things. I already knew how these motors worked, but you had me watching with interest all the way through. Thanks. ...... now it's my 6 year old's turn to watch - let's see how he goes...
Hello Matthias, I really was impressed when watching your video. As a professor I am preparing my lesson about electrical motors, but up to now had it seen from the theoretical point of view. Your video not only demonstrated that theory works well in practice, but gave me a push in understanding this tiny but mystic machine. Thank you. If you don't mind, I am going to use your video for my lessons, after translating it in german (as I am teaching in Cologne, Germany) and reassembling audio and video with an editing software.
I have worked with electric tools for many years and never took the time to figure out how they work. This was a good explanation. Thanks Matthias for this nice tutorial.
Great video Matthias! That was very interesting to watch, and had my attention the entire time. I liked the visual display of the rotor spinning outside of the drill.
Thank you Matthias that was & great explanation, I've just been watching your fathers shop tour he will be very proud of you your a very clever man, my mission is to build my own bandsaw buying your plans of course, keep up your great work my friend regards Mark.
Wow thanks brother. All the videos out there say "Easy Basics of BLDC, ac, &/or induction motors" but never tear into the motors and physically show the functions of parts included. And your homemade demonstrations of the parts broken down is AWESOME! thanks for the extra effort.
I am amazed by you're intelligence Mathias. I work in industrial maintenance and I've had lots of training and experience with different kinds of motors. This 7 minute video explanation is a great learning tool that is easy to understand. Very well done
My dremel is broken, and i have been waiting until i have the knowledge to fix it... And now i can! I found out that the brushes have been worn out. Thanks for the technical video, I would love to see more of these. :D
Matthias you have a wide variety of knowledge, not only as a woodworker and carpenter but also as an electrician and electronic engineer. You make me wonder "What is he gonna think of now?" at the start of every video you upload and leave me saying "Damn!" at the and of each one. Thank you very much and congratulations on the progress you have made in your life.
I think I only understood like 40% of this video, but this is my first time learning about motors and how they work so I'll just keep watching your videos and hopefully one day I'll be an expert on them. Thank you for the useful videos!!
ive taken University Physics, Physics 2, AC DC circuit's, and Intro to EE (I'm studying Mechanical Engineering) and this is the best illustration and explanation i have witnessed I love your home made work shop and the scientific mind you have!!!
excellent video... I just repaired the trim motor that controls the outboard motor on my boat... this helped me to understand what the hell I was cleaning up... brushes, springs, commutators, stators.... you rock!
Came to the comments right after I saw it to see if anyone else caught that. It really is a great practice. I get a kick out of people that are this stupid. Keeps the Darwin awards coming. Not surprised thought to see such terrible tool handling practices....... He is a filthy wood elf after all.
You know, I bet the thumbs down are accidental, I was taught this and have taught this occasionally for over 40 years, this is by far the best explanation I have ever seen. There was a science book from, I think the 50's or 60's, that showed how to make a dc motor with a long sewing needle, a cork, several straight pins, some insulated wire and a horse shoe magnet and a 6v lantern battery. It was pretty cool too.
"Home made voltmeter..." Yes, yes, place that voltmeter right next to the home made wifi antenna, home made tractor, home made guitar, home made full-sized yacht, home made space shuttle, home made fully functional and sentient Optimus Prime - no need for Transformium, no less - and home made large hadron collider. Matthias, we love you and all, but try to soften the blow when you make us feel like underachievers, ok?
Thanks a lot for this amazing explanation of the actual motor, most of the videos out there show animated ones but in this one you showed us a real motor. Thanks again!!
Really appreciate this. It was a well laid out explanation and I've always been curious about this kind of stuff. Look forward to the induction motor video. Thanks!
You're knowledge of electric motors is really great & well explained in you're videos. I am planing connecting a 240 washer motor to 12 v DC & will probably need you're help with which connections two pair up. Many Thanx........ Stan the Man.....
I'm guessing those 7 (now 14) were either just dumb or Safety Nazis that thumb's downed because Matthias stopped the circular saw blade by pressing down near the arbor with his fingers. Safety Nazis need to get a life!
Fabulous. Not being my domain I know little about motors, but always wanted to use them in future projects given I am retired. The subject of motors can quickly get complicated, so your explanation of the Universal motor was most welcome especially since it seems to be the easiest for beginners to tinker with.
Excellent! Your video is very, very well done and greatly appreciated. I am a retired teacher of science and appreciate someone who can pass knowledge so well. Best of luck and we'll certainly watch your other videos.
This is the best video I've seen that describes how the DC motor works. Forget all the fancy graphics, there is nothing better than someone actually demonstrating it with actual components from a very basic perspective. I have a video coming up that shows a very old (1905 in fact) elevator machine room. There is a DC motor in use and I'm going to briefly explain it, with a link to your movie for a full explanation.
Excelent presentation. Nowdays, universal motors are mainly used, which for me is a surprise, because nobody mentions them. I was opening a hair dryer and noticed that the motor inside is brushed and didn't have permanent magnets, but it is directly connected to AC source, without a bridge rectifier, so I was surprised. Thank you
Man youre the best physics teacher ive ever had , you made it super clear for me how these uni motors do theire jobs an all time dilema for me ! Great job
I have been watching every other video hosted by engineers with fancy animations explaining how the motors work and your video is the best by far. Thank, I know I will pass my electrical test tomorrow
That's such an awesome explanation of DC motors! The best things you did were to explore a real DC motor and show its limitations! I had some laboratories about DC motors in my uni., but there i didn't even learn 10% of what i learnt through this video! Cheers mate!
I've been gaining curiousity of how these work recently, but never really understood it. I understood within 3 minutes of this video. Probably because he used an actual motor instead of diagrams. Thank you!
Wow! You've inspired me with your wonderful explanation, to take apart a non-working electrical weed whacker motor and see whats going on. Thank you so much for sharing you knowledge.
EXCELLENT!! And the sad part of that is that your skill at presenting really should be the NORM! You stand out because you never said, "Uh" or "Um..." or "You know..." and your camera didn't SHAKE or PIVOT wildly about and we didn't have to listen to you breathe into the mic. Or grunt into the mic. And we didn't have to wait for you to try to remember what to say next..Nor did we have to listen to the unnerving, banging sounds of you dropping things as you looked for your tools or components.Again, EXCELLENT! Very informative! A pleasant and satisfying viewing experience! Thank you, sir.
I am an electrical engineer that has experienced for 7 years. And when i opened this video, i believed i would watch an another boring explanation. But after then i really impressed. At the university on electrical machines course we just wrote and wrote for tens of papers of boring theories, at the laboratory just another boring stuffs such as short circuit condition , no load condition etc. Was that difficult to show students, this kind of easy demonstrations step by step? All students could visualize what happens on motor then they could embrace all theories behind easily. So thanks a lot
Hello Matthias, I have just found your channel and your content is very, very good. Much better explanations that what I got from my teacher at the university. Keep up the good work!
The best videos stimulate curiosity, and this one did it for me. I paused for a moment to understand the back EMF at 3:56, the fundamental basis for a generator....
Great explanation and demo. I wish I could have seen this when I was in high school. Back then motors were black magic and things to be admired and feared.

As a retired schoolmaster I envy your ability to explain such a, potentially, complex subject in such an interesting way.
Love they way in which you explain things, always a wealth of knowledge!
This has been explained to me before but the visual makes it much clearer! Thanks Matthias.
You are really wonderful at explaining things. I already knew how these motors worked, but you had me watching with interest all the way through. Thanks. ...... now it's my 6 year old's turn to watch - let's see how he goes...
Now its 12, how did it go???
This was honestly the best way I have ever heard this explained

Very good explanation of how a common motor works.
Thanks for the video Mathias,
Roland
great technical info ... thanks Mattias
Colin
I always love taking things apart and see how they work thanks :)
I have worked with electric tools for many years and never took the time to figure out how they work. This was a good explanation.
Thanks Matthias for this nice tutorial.
Your test rig with the rare earth magnets gave me a great idea for a project. Thanks!
Really great explanation! Thanks!
Hell yeah, this just is so well explained that it's downloaded into my memory now.
I've seen, read and heard heaps of DC and AC motor explanations, and Matthias sums it up beautifully in less than 10 mins!!!
Great video Matthias! That was very interesting to watch, and had my attention the entire time. I liked the visual display of the rotor spinning outside of the drill.
Thank you Matthias that was & great explanation, I've just been watching your fathers shop tour he will be very proud of you your a very clever man, my mission is to build my own bandsaw buying your plans of course, keep up your great work my friend regards Mark.
You do a great job explaining this to someone who isn't familiar with this topic. Thank you!

thats brushless
Very helpfull,tks

Best motor/magnet explanation I have ever heard or given.
Matthias Wandel ,, thank you sir for the very clear explanation and the amazing video.

Thank you Matthias for taking the time to make such a good video.
I think I only understood like 40% of this video, but this is my first time learning about motors and how they work so I'll just keep watching your videos and hopefully one day I'll be an expert on them. Thank you for the useful videos!!
i couldn't be more fascinated. great video. are all induction motors brushless?
I was always curious what they meant by brush vs brushless motors. Thanks Matthias!
realyy???
ARTASH SARGSYAN No. The contacts on the slot car shoe were there to provide voltage to the brushes on the car's motor.
ARTASH SARGSYAN good
ARTASH SARGSYAN .
Brushless is nowadays almost an AC motor in all but name.
Well done, finally a demo on converting a universal motor into a DC motor, you saved me a lot of time, thank you very much indeed.
I've seen some great explanations of how DC motors work, but the visual demonstration with a real rotor takes this waaay over the top. Thank you!
Wow, after 26 years I finally get it!
You would be very valuable in a real classroom!
You explained and clear out so many things for me, thank you!
I ve watched many of your videos and I have made furniture out of your plans. You are a gifted teacher.
Bah I thought Matt was going to build a superhero suit from DC Universe: Motor Man!
But this video is also good.
My god... *eye roll*
awesome video, if only my college teachers would have explained it like that.......
Many teachers lack the art of teaching
Johnny D
The irony is that those who should actually be teachers, don't want work as teachers. And vice versa. Often same for politicians too
Bala Kumar Don't spam.
ive taken University Physics, Physics 2, AC DC circuit's, and Intro to EE (I'm studying Mechanical Engineering) and this is the best illustration and explanation i have witnessed I love your home made work shop and the scientific mind you have!!!
I went through many videos on youtube reagrding DC Motors but after watching this video my concepts are far better now..Thank you
In an end of the world situation where only 100 people get to leave earth on an ark, Matthias would get a ticket.
not me. no ticket for me. i'm not doing anything unique or important.
I'd want him to design the ark too
Excellent demo!
O9lk
So if I want to make a generator instead of having a laminated core made up of many small sections I just have a solid steel core since I want emf?
i wish u were my science teacher
excellent video... I just repaired the trim motor that controls the outboard motor on my boat... this helped me to understand what the hell I was cleaning up... brushes, springs, commutators, stators.... you rock!
Thanks for sharing this! You are a very good teacher.
wish i had a physics teacher like this back in school :-/
My favorite part is when he stopped the circular saw blade with his hand.
Noble909 Strangely enough, the safety trolls have not picked up on that!
It's not that dangerous
Matthias has settled down somewhat, remember when he used to use his tongue, ahhhh, those were the days, ribbet!
Came to the comments right after I saw it to see if anyone else caught that. It really is a great practice. I get a kick out of people that are this stupid. Keeps the Darwin awards coming. Not surprised thought to see such terrible tool handling practices....... He is a filthy wood elf after all.
I like the part where he stops the blade with an orphans softspot
This is the best explanation of a motor I have ever seen, heard, or read. Thank you, sir!
You know, I bet the thumbs down are accidental, I was taught this and have taught this occasionally for over 40 years, this is by far the best explanation I have ever seen.

Yes, yes, place that voltmeter right next to the home made wifi antenna, home made tractor, home made guitar, home made full-sized yacht, home made space shuttle, home made fully functional and sentient Optimus Prime - no need for Transformium, no less - and home made large hadron collider.
Matthias, we love you and all, but try to soften the blow when you make us feel like underachievers, ok?
Surely all large hadron colliders are homemade.
You can hardly buy them on amazon.
:-)
Lol
0:04 Did know one else see that?!?
I'm guessing you're surprised that he touched the spinning saw
what? you never saw a man touch a smooth spinning surface before?
:0
Thanks a lot for this amazing explanation of the actual motor,
most of the videos out there show animated ones but in this one you showed us a real motor.
Thanks again!!
Really appreciate this. It was a well laid out explanation and I've always been curious about this kind of stuff. Look forward to the induction motor video. Thanks!
Hard to believe somebody that can make their own voltmeter would stop a saw blade with their hand
tnf. the cutting section of blade was well guarded when he stopped it by hand..
There's a difference between knowing your tools and being some dumb safety nazi commenting on youtube..
You're knowledge of electric motors is really great & well explained in you're videos. I am planing connecting a 240 washer motor to 12 v DC & will probably need you're help with which connections two pair up.
Many Thanx........ Stan the Man.....
7 people didn't get it
I'm guessing those 7 (now 14) were either just dumb or Safety Nazis that thumb's downed because Matthias stopped the circular saw blade by pressing down near the arbor with his fingers.
Safety Nazis need to get a life!

Lost me about 5 seconds in to this video!
You mean when he stopped the circular saw with his hands? @0:05. Safety Man!!
I recoiled my fingers so fast when he did that.
Get over yourself...
Oh look, another safety Nazi that isn't good at anything else. You sure you and I didn't serve in the same Army unit?
amazing video, makes me apreciate even more how cheap and available these things are
That is the best demo I have seen on universal motors.

You are one of top guys on TH-cam who explain things amazingly clear without any 3D animations 👍
This is really well explained Matthias, thank you and great job.
Man youre the best physics teacher ive ever had , you made it super clear for me how these uni motors do theire jobs an all time dilema for me ! Great job
That was so helpful, I finally understand how motors work. Thank you so much!
Thank you Matthias for the great explanations
Thank you for taking the time to show us how a motor works
Such a good and useful video!
Thanks Matthias! That was very well explained!
You are a good man
Your videos are so useful for us here in Qatar and Egypt
Thank you one million times
Thanks for the easy to understand explanation! I am slowly getting this!
Your review is very helpful for me, thank you!
I have been watching every other video hosted by engineers with fancy animations explaining how the motors work and your video is the best by far. Thank, I know I will pass my electrical test tomorrow
@2:22 you got a WOW effect for the clear explanation of the way these motors work. a BIG thumbs up 👍
Fascinating! Thanks Matthias!
Simple and direct tutorial.... and now i know what is wrong with my old cordless drill. Solid work man
That's such an awesome explanation of DC motors! The best things you did were to explore a real DC motor and show its limitations! I had some laboratories about DC motors in my uni., but there i didn't even learn 10% of what i learnt through this video! Cheers mate!
Fascinating! I learned more from this one video than I did in 2 years of Physics lessons at school.
I've been gaining curiousity of how these work recently, but never really understood it. I understood within 3 minutes of this video. Probably because he used an actual motor instead of diagrams. Thank you!

right🤩
Omg, I just had an epiphany. This was brilliantly explained. Thank youuu!
your desktop power boxes are awesome nice work
